Witchlaser ult comes from Phighting, the team based multiplayer fighting game on Roblox known for its stylised phighters and ability driven matches. Ultimate sounds in the game are designed to be recognised instantly during fast fights, signalling that a stronger move is about to change the round. Fans lifted short ability clips like this one for soundboards because the charge and blast are identifiable even without gameplay on screen. It remains popular in Roblox edits and fan videos where a brief, magical laser cue is needed.
